- Introduction to the Induction Rail Coil Gun.
Basically the Induction Rail Gun is a UNI Rail design where a ring of magnetic flux travels down the rod or rail to repel the copper or brass projectile.
Watch how I wind a tight clean coil with 14# wire with no end caps to contain the wire from falling off.
About 2 inches in length.
3/8 Steel Rod
11 layers
#14 Wire
0.15 Ohms DCR
1.75 mH
I switch to this topography because only one coil is needed and most likely several pulses will be needed to get to proper operation.
Also less weight and size.
Surely a coil with just two connections can only be an inductor not a transformer?
Maybe, maybe ... Oh sure.

Is this a coilgun, or a railgun? It can't be both. The work similar but on very different principles as in one has a coil and barrel while the other has rails and no coil.
I would love to see the power supply plans you talked about makeing. Thanks for coming back!
Thats a struggle to do alone man nice work!
Hello: As you stated: you are winding 11 layers of 14 AWG magnet wire (can I use 12 AWG--I have lots of this and no 14 AWG). I assume that each successive layer has a couple of less turns. Can you tell me how many turns went on the first and last layers?
How many metter of copper wire did you use for make 1 coil ?
Maybe, maybe ... Oh sure.

I am hoping multiple pulses will have to be delivered to the coil to achieve the results
YES more coil GUN stuff!
You think a uni rail coil gun will work better than your first coil gun?
You're using a two rails for the railgun with a coil at the beginning?
Maybe, maybe ... Oh sure.

Clay, Can you tell me what kind of tape that is you are winding around the coils--the different colors of the tape look like they are different widths. I assume it's conductive--from the all too familiar sounds I hear! I have several rolls of insulative yellow "transformer tape"...don't know where this would be useful. Aren't you worried about the eddy current effect of the conductive tape surrounding each layer killing a bit of the self-inductance of the coil?
Thanks again.
dale nassar metallic mylar type
I have plans to make a longer coil. What's the odds if it were several times longer than this?
Yes, so I assume you'll control those pulses via a microcontroller to the SCR once again?
I have some stuff to do this experiment, I may have wound this coil to beefy. I need not have enough capacitance to run it I have some other smaller wire. I'm going to send you a link to a video
they were using electrolytic 500 volt in series and maybe more in series but that's not really a good way to do that you should use a regular 2000 volt capacitor but I know it's hard to get them
Will you use capacitor discharge like the previous one or several lithium batteries?
What if you use a magnet for the bullet? I don't see anyone trying this.
Because magnets don't work you have to use steel low carbon content
Hello ...Clay...? Is that the right name. I am still interested in your coil array, but plan to modify it a bit. I am using critical damping along with other method on coils down the line. After seeing you wind that thing, I do not want to repeat that process!! The method I am going to use is for research timing with various turn-on methods. I have decided to use the Phillips bits, and that is why I need to know the unloaded inductance as well as the loaded inductance (measured with a simple passive "L-meter". I hope you can supply this. Also, since I am familiar with the coil-driving mathematics of the coils, I will, if possible, try to help you in any way if I can. I use a very cheap LCR meter that goes from 2uH - 200uF (bit on the high side). Cost: about $18.
Thanks much...again,

Whatever became of this? This is really interesting using a single coil to create a pseudo railgun with an oscillating current. Might be able to use it to fire aluminum arrows or crossbow bolts, provided the internal resistance isn't too high.
I basically had to sell my house so I had to stop doing everything and clean and paint and it was a stress pit. Now I moved and everything but I don't have no money to invest into making projects that basically I can't be used anywhere except to Fascinate people
@@RaptorRotorHead Ah gotcha man. "Life's a bitch and then you die" as they say. Best of wishes.
Did you ever get anywhere with this?
why can't you fix it to slow turning power drill to wind the Coil
Для фиксации витков катушки используй супер клей. Липкой лентой не удобно работать.
I remember you saying I will put a brass point on them , I tried it with aluminium tip for my projectile . what happened was significant slowing down of projectile how did it go with your gun did you try brass printed projectile??
Vasudev Mr I have not done anything with this induction rail yet I think the secret is to win the coil into a flat pancake Because by the formula that's the most magnetic force
Clay Reid no no I was talking about the projectiles in this video . did you shoot a brass tipped projectile when I shot aluminium tip projectile it had significant speed reduction .
I used a brass washer flat and I think I got worse results than you. I mean I have enough capacitors I would have to put a scope on it and look at it.
Tankyou my frend this is good way for winding coil
Hello Clay,
How can I turn OFF (fast) one of the standard SCR? It is for a special application. No one else seems to know...I have no GTO type SCR's...I'm sure you will know.
Thanks much,
Silicon controlled rectifier is just fancy american name of thyristor and you can't turn it off when it's conducting. For your aplication you must change it to gate turn off type thyristor or IGBT.
I'm an amateur but, if water is a polar molecule could you shoot ice through the coil gun?
Michael Hallett no he cannot shoot ice
What is that tape that you insulate the different layers with?
ryccoh that is metallic mylar tape.
is a coilgun that uses of rail of magnetic flux round rod
Have you done any real coilgun research or building? Is this your first one. Firstly you cannot use a metal barrel unless you cut a slot the full length to break the circuit it creates. It acts like the secondary of a transformer. So the eddy currents created in it rob you of the majority of your power. That is why if we are left with no choice in out design but to use a metal barrel we cut a slot in it for it;s full length before the coil is wound. The barrel in a coilgun serves no purpose but as a coil form and to protect the inner windings in the event the round was to strike them. There is no magnetic force that is traveling along your barrel, pulsed or otherwise. Sorry to break this to you. I have built these guns for years and have tried all sorts of tricks. This design has one function and one function only. When the coil is energized the round is pulled in to it. The coil is then de-energized right before round reaches the center threshold and starts getting pulled back by the coil. The round then travels via kinetic energy only the rest of the way. If this was a multi coil then each coil would repeat the previous process imparting more velocity and energy into the round.
What you might be thinking of is an induction coilgun which is different from this model that is a reluctance coilgun. With an induction coilgun the coil is wound flat and the projectile is a ring made of non ferromagnetic material like aluminum or copper. The coil can also be shaped like an inverted cup that the ring sits halfway into. The way that works is when the coil is energized. The ring generates an opposing field of the same magnitude against the coil thus pushing the ring away from the coil at high velocity. These are often called ring launchers but you can get creative and configure them to launch horizontally as well. A rappel ring woks very well as the rounded cross section makes it somewhat aerodynamic
Solarenemy1 we like to experiment but if you want to see something watch this.

Sorry to bother you, but I can't find part 2 anywhere!
dale nassar that's because there's no part 2 yet, I'm in the process of selling my house and moving to Arizona next state over
This looks fun🤔
Oh sure.

you showed me a video few days age , did you notice what type of cap bank they were using . they were using high energy pulser 5 kv cap bank . and I soldered a cap bank of 2000uf at 1000v and tried and the results were better .
Vasudev Mr Drive 4000 microfarad
Clay Reid yes I will increase the thickness of my wire and I will machine a proper projectile out of brass and use a big cap bank . when will you do part 2 ??
Yes
Vasudev Mr 3-4 days I have to cut open the other coil gun to get the electronics out of it. a bad battery caused the computer to malfunction and the power supply fet were destroyed.
How is the "tape" you put between layers called?
I second that.
I need additional equipment, wire spool holder foot pedal speed control. and vertical winding is hard better horizontal.
just pay some kid with attention to detail to wind for you hahaha
I see those projectiles in video will they penetrate steel sheet
Vasudev Mr they would if you put a point on them
thanks for posting. guess you hope to create monster eddy currents in a non-ferrous hollow cylinder projectile, as magnetic flux propagates along the shaft. i doubt its practical/possible to impart mechanical energy in this way.
take a look at my idea, if it suits. cheers
David Davids I've already built coil guns, I have other videos I've been penetrating steel plate .062

watch this.
What is the approximate inductance range of EACH of the YAK coils with an empty core? I am specifically speaking of EACH stage (not a sum) for one coil of the 6-stage coils in the one you are selling.
Thanks much,
--dALe
About 300uh
The inductance changes a little from coil to coil, checking with a lcr meter.
@@RaptorRotorHead I really appreciate that. Did you happen to check the inductance when the projectile is centered in it?
Thanks much,
@@dalenassar9152 you cannot connect an lcr-meter when there's 400 volts on the coil it would destroy the meter.
@@RaptorRotorHead Thanks for the reply. I was speaking of just connecting a simple inductance meter to the coil--that is the only way I have done it, with accurate results. Is the price on that coil set still up at $200.00?
How did the "Rail" come in?
NNNI It's using a rail to be induced by the coil, creating a magnetic field around the projectile, pushing it forwards. I think. Never seen this kind of coil gun yet.
I was thinking more of the rod...
I'm blank on this one too... so far.
OH yeah, Clay:
A thought: will simply shorting the terminals of the main firing SCR, with another similar SCR turn OFF the main SCR (by pulling it below holding current?). Or even shorting the main capacitor?
Thanks for all your information. I finally found a way to control the multiple/identical gates of your six-shooter on the 4HV.ORG FORUM, under "Electromagnetic Projectile Accelerators". Under the title: 'Maximum speed in multistage accelerator with ==identical windings==: 12-23-2018
what stuff you don't have to do this experiment ??
Vasudev Mr probably in about two months on that same bench is 2 band saws, and a Grinder. I don't have any room at the moment and I need these tools up for wood for the fireplace

sir can you send induction rail coil gun part 2 video link
Ah nice, what will part 2 be about?
Azagro it will be about shoot the projectile
Vasudev Mr Yes, I read that
What is that green tape that you put on the coils?
ryccoh metallic mylar
What reason do you use it for? If it's metallic can it not interfere with magnetic field or be induced with eddie currents?
ryccoh it just looks metallic it is not metallic it is Mylar. but I gave you the exact name of it in case you wanted to obtain it on the internet.
ryccoh I use it to hold the layers of wire together so that each layer can be wound easy.
When will part two be coming out?
Ty Coleman soon as I build me a power supply that won't blow out. I'm designing it right now as a matter of fact.
Holy shit you wind those by hand :| It took me like 5 hours to build a winding machine with 3d printed parts and 12mm axle stock + an old brushed DC motor.
capacitor discharge only way to get max power
what kind of wire do you use ?
16 gauge wire.
@@RaptorRotorHead thanks
part 2 we'll be testing this thing.
you have not seen the videos I have seen on TH-cam.
Clay Reid do you live around the country side? im just curious
Gummy Down yes.
Clay Reid is it great living out in the coubtry side?
aye captain
Lol, this would work off the house AC power

Unless you are using two parallel rails then this is only a coilgun with a guide and nothing more. Please stop mixing terminology.To give this an exact name, the normal coilgun is called a Reluctance Coilgun. Your is called an Inductance Coilgun and nothing more. Leave the railgun part out of this.
Your mouth is dry drink some water please.
No I used to smoke weed now I don't.
@@RaptorRotorHead oh well, thanks for taking the time to reply.
